Abstract
Of 105 isolates screened for growth on plates containing olive mill wastewater (OMW), five were selected and identified as Pichia fermentans (Y1, Y4) and Candida sp. (Y2, Y11, and Y18). On the basis of their ability to use phenol at 716 mg l−1, strains Y2 (15% reduction) and Y4 (18% reduction) were then used to detoxify stored OMW under various operational conditions. Yeast treatment of OMW increased the pH and, in the best conditions (aeration and no glucose addition), the COD decreased (47%) and phytotoxicity was also decreased (56%) probably due to the changes in the composition of phenolic compounds.
